Description

Technical Field

[0001] This utility model relates to the field of material receiving platform technology, and in particular to an underground openable material receiving platform. Background Technology

[0002] In the bucket hoisting system of mine tunnels, strict regulations apply to bucket loading operations to ensure operational safety and equipment stability. According to industry standards and operational safety guidelines, when loading in vertical shafts, the bucket must be precisely positioned at the bottom of the working face. When loading in horizontal tunnels, it must be placed on a closed, fixed, or non-transferable loading platform. This bottom support design effectively counteracts the impact forces generated during loading, preventing the bucket from swaying, tilting, or even falling due to uneven force distribution, thus ensuring the safety and stability of the loading operation. In the complex and ever-changing mine shaft development projects of today, there are often special working conditions involving multi-level hoisting and reliance on bucket hoisting. In such situations, the bucket needs to frequently move between different working levels, and loading operations are required at each level. However, due to the limitations of the working environment and space at each level, it is difficult to install a bottom support structure at every loading point. This results in the bucket lacking effective support at the bottom during loading. Loading operations without support are prone to violent shaking of the bucket and material spillage due to the impact force, severely affecting loading efficiency and the accuracy of material transportation, and posing significant safety hazards, threatening the lives of underground workers and the normal operation of equipment. Therefore, this utility model proposes an openable underground material receiving platform. Utility Model Content

[0003] The purpose of this utility model is to address the problem in the background technology where the hoisting bucket needs to frequently shuttle between different working levels and perform loading operations at each level. However, due to the limitations of the working environment and space at each level, it is difficult to set up a bottom support structure at each loading point. As a result, the bottom of the hoisting bucket lacks effective support during loading. Loading operations in this unsupported state can easily cause the hoisting bucket to shake violently and materials to spill due to the impact force of loading. This not only seriously affects the loading efficiency and the accuracy of material transportation, but also brings great safety hazards, threatening the lives of underground workers and the normal operation of equipment. The present invention proposes an openable material receiving platform for underground operations.

[0004] The technical solution of this utility model is as follows: an openable material receiving platform for underground mining, comprising: a material chute fixedly installed on the well wall for guiding materials, a bucket for receiving materials located at the outlet end of the material chute; a base fixedly installed on the well wall, the upper surface of the base having a hoisting opening, the upper surface of the base having two guide grooves, and the guide grooves being located on both sides of the hoisting opening and communicating with it; and a blocking component installed above the hoisting opening for supporting the bucket.

[0005] Optionally, the blocking assembly includes a sliding baffle slidably disposed inside the guide groove. A set of support plates are fixedly disposed on the upper surface of the sliding baffle. A top plate is fixedly disposed on the upper end of the support plate. An electric push rod is fixedly installed on the upper surface of the base. A connector is fixedly connected to the output end of the electric push rod. A set of connecting rods is rotatably disposed on the connector. A connecting seat is rotatably connected to one end of the connecting rods. One end of the connecting seat is fixedly connected to the support plate.

[0006] Optionally, a support is fixedly installed on the bottom surface of the discharge chute, and the support is fixedly connected to the well wall.

[0007] Optionally, supports are fixedly provided on both sides of the discharge chute, and the supports are fixedly connected to the well wall.

[0008] Optionally, a limiting plate is fixedly installed inside the guide groove.

[0009] Optionally, the support plates may have different heights.

[0010] Optionally, a baffle is fixedly provided on the upper surface of the top plate, and a reinforcing plate is fixedly provided on one side of the baffle, with one end of the reinforcing plate fixedly connected to the top plate.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model achieves effective support for the bucket by using a blocking component set above the hoisting opening. Specifically, it consists of a linkage structure composed of a sliding baffle, a support plate, a top plate, an electric push rod, a connecting rod, and a connecting seat. When the bucket is being loaded with slag, the electric push rod pushes the connecting rod, causing the sliding baffle to slide along the guide groove. The support plate and the top plate form a stable support surface, preventing the bucket from shaking violently due to the impact of loading slag, effectively preventing material spillage, improving loading efficiency and the accuracy of material transportation, and ensuring the safety of underground operations.

[0013] Furthermore, this utility model achieves comprehensive and stable support for the bucket during material receiving by fixing a baffle on the upper surface of the top plate and connecting a reinforcing plate to one side of the baffle and fixing it to the top plate. During the material receiving process, the baffle can effectively prevent the bucket from lateral displacement caused by the impact force of loading, while the reinforcing plate, by forming a stable triangular support structure with the top plate, enhances the baffle's resistance to deformation, reduces structural shaking caused by external impact, provides a solid and reliable support surface for the bucket, greatly improves the stability during the material receiving process, reduces the risk of material spillage, and ensures efficient and safe underground loading operations.

[0028] Example

[0029] like Figure 1 and Figure 4 As shown, the present invention proposes an openable material receiving platform for underground wells, comprising: a material chute 1 fixedly installed on the well wall for guiding materials; a support 7 fixedly installed on the bottom surface of the material chute 1, with the lower end of the support 7 fixedly connected to the well wall; supports 8 fixedly installed on both sides of the material chute 1, with the supports 8 fixedly connected to the well wall, enabling stable installation of the material chute 1; a bucket 2 for receiving materials is installed at the outlet end of the material chute 1, and a hoisting mechanism is installed above the bucket 2, which includes a winch, a hoisting rope, and control components, which are existing technologies and will not be described in detail here, enabling vertical lifting of the bucket 2.

[0030] Furthermore, a base 3 is fixedly installed on the well wall, and a hoisting opening 4 is opened on the upper surface of the base 3. The hoisting opening 4 facilitates the passage of the bucket 2 to achieve vertical up and down adjustment. Two guide grooves 5 are opened on the upper surface of the base 3. A limit plate 9 is fixedly installed inside the guide groove 5, and the guide groove 5 is located on both sides of the hoisting opening 4 and connected to it.

[0031] like Figures 2 to 5As shown, a blocking assembly 6 for supporting the bucket 2 is provided above the hoisting opening 4. The blocking assembly 6 includes a sliding baffle 61 slidably disposed inside the guide groove 5. A set of support plates 62 are fixedly disposed on the upper surface of the sliding baffle 61, and a limiting plate 9 is located between the support plates 62 to facilitate limiting the sliding baffle 61. The support plates 62 are at different heights, and a top plate 63 is fixedly disposed at the upper end of the support plate 62, which can tilt the top plate 63 to stably receive the material discharged from the discharge chute 1. An electric push rod 6 is fixedly installed on the upper surface of the base 3. 4. The electric push rod 64 is equipped with a rechargeable power supply and signal control components, which are existing technologies and will not be described in detail here. The output end of the electric push rod 64 is fixedly connected to a connector 65. A set of connecting rods 66 are rotatably mounted on the connector 65, which enables the electric push rod 64 to push the connecting rods 66 to move simultaneously through the connector 65. One end of the connecting rod 66 is rotatably connected to a connecting seat 67. One end of the connecting seat 67 is fixedly connected to the support plate 62, which enables the support plate 62 to move simultaneously through the connecting seat 67, thereby realizing the automatic opening and closing of the hoisting opening 4.

[0032] Furthermore, a baffle 10 is fixedly installed on the upper surface of the top plate 63. The baffle 10 can limit the movement of the bucket 2 to prevent it from sliding when receiving materials. A reinforcing plate 11 is fixedly installed on one side of the baffle 10. One end of the reinforcing plate 11 is fixedly connected to the top plate 63. The reinforcing plate 11 forms a triangular structure with the baffle 10 and the top plate 63 to improve the stability of the support.

[0033] The working principle of this embodiment is as follows: When carrying out underground muck loading operations, the material slides through the discharge chute 1 into the bucket 2 below. Since the top plate 63 is inclined, the stability of the bucket 2 in receiving the material is ensured. During the receiving process, the baffle 10 located above the top plate 63 provides a limit for the bucket 2, preventing the bucket 2 from sliding due to the inclination of the top plate 63.

[0034] After loading is completed, the hoisting mechanism is activated to lift the bucket 2 vertically upwards. At this time, the blocking component 6 located above the hoisting opening 4 begins to operate. The electric push rod 64 is activated through the signal control component, and its output end pushes the connector 65, thereby driving the connecting rod 66 to move. The rotation of the connecting rod 66 causes the connecting seat 67 to move the support plate 62. The support plate 62 pulls the sliding baffle 61 to slide along the guide groove 5, and the sliding baffle 61 opens the blocked hoisting opening 4.

[0035] Afterwards, the hoisting mechanism is activated to move bucket 2 vertically downwards until it is stably hoisted to the bottom of the well, which effectively improves the efficiency of loading and unloading and the accuracy of material transportation, ensuring the safety and efficiency of underground operations.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
